To aZZaohom it may concern:

Be it known that 1, DAVID HINDAHL, a

citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to dump cars, and more particularly to dump cars which are convertible from a hopper bottom to a flat bottom arrangement, and vice versa.

in the regular Hart convertible car, as shown in his Patent No. 827,632, granted July 31, 1906, the end pieces of the car shown are solid and are movable in position from the end of the car to the end of the hopper in a manner to form the end structure of the hopper when the ear is being used for center dump work. There are certain advantages in permanently securing the solid end pieces in place at the ends of the car. On the other hand, it is advantageous to have removable members which may form the end structures of the hopper when the car is being used for center dump work. Referring again to the Hart patent in question, it will be noted that floor doors are shown which cover the hopper when the car is used as a flat bottom car, said doors being swung upwardly and outwardly to form continuous hopper portions when the hopper bottom arrangement is desired. The hoppers must be covered when it is desired to convert the car into a flat bottom car and at the same time the removable hopper ends must be shifted from their normal positions in order to present an unobstructed fiat floor portion through the length of the car.

By my present invention, when it is desired to form a flat bottom arrangement, the hopper and structures are remo ed from their normal positions and placed over the parts of the hopper, to present fiat floor, the remaining part of the center hoppers being covered by pivotally mounted floor members which when the car is arranged as a hopper bottom car occupy a position on the floor between the ends of the car and the removable hopper ends. The sides of the car may be moved from a vertical position in which they are mounted when a flat bottom arrangement is used to an inclined position wherein they form portions of the hopper walls.

The object of this invention is to simplify and improve convertible cars in a manner whereby various parts thereof perform a plurality of functions, and cooperate in a novel manner to meet the requirements for successful commercial use. 7

These and other objects are accomplished by means of the arrangement disclosed on the accompanying sheets of drawings, in wh1ch Figure l is a fragmentary side elevation of a convertible car embodying my inventlon,

F 1g. 2 is a longitudinal sectional view of the same car showing a fiat bottom arrangement.

Fig. 3 is a fragmentary plan view of the same car showing the flat bottom arrangement,

Fig. 4 is a fragmentary plan view showmg the hopper bottom arrangement.

Elg. 5 is a transverse sectional view showmg the hopper bottom arrangement, and F 1g. 6 is a transverse sectional view show- 1ng the flat bottom arrangement.

The various novel features of my inventlon will be apparent from the following description and drawings and will be particularly pointed out in the appended claims. Referring to the figures of the drawings, it will be noted that l have provided a dump car including sides 10, ends 11 and a bottom including fixed horizontal portions 12 at the ends of the car. Intermediate the fixed portions 12, the bottom of the car is provided with a central hopper 13 including a dump door 14, by means of which the load, or a portion thereof, may be dumped between the rails. The load also may be dumped to the outside of the rails by movmg the floor doors 15 into an open position, thereby providing for side ballast work in addition to center ballast. Normaliy floor doors l5 occupy a horizontal pO SlblOfl and extend the entire distance between the stationary floor portions 12.

When the car is arranged as a hopper bottom car, the side members 10, which in one position form vertical side portions of the car, occupy inclined positions substantially in the same planes with the hopper dump door 14 and its cooperating hopper member 16% respectively. These side members 10 which are adpistable from their vert1cal position, shown in Fig. 6, to an inclined position, shown in Fig. 5, are supported at their lower ends by suitable angle members 17, their upper ends being supported by side sheeting 18 forming a closure for the sides of the car at the upper ends thereof when the side members 10 are in inclined posltion. These side members 10 preferably are floor portion 12 from the hopper portion of the car. When the car is arranged as a fiat bottom car, the member 19 acts as a floor ortion (.see Figs. 2 and 3) which lies in a horizontal position and covers part of the central hopper 13, one end of the member 19 in such position being located at the transverse center-line of the car, the other end of the member 19 extending toward the end of the car. The remaining portion of the hopper 13 at each end, with the fiat bottom arrangement, is covered by a pivotally mounted member 20, the swinging edges of which abuts the outer end of the member 19 forming a horizontal fiat floor throughout the entire length of the car, it being understood that there are two members 19 and two members 20 for forming the complete cover for the hopper portion13 of the car. When the car is arranged as a hopper bottom car, each of the pivotally mounted members 20 is swung from a position over the central hopper 13, as shown in Figs. 2 and 3, into the position shown in Fig. 4C, in which position the member 20 occupies a portion of the stationary floor portion 12.

As shown in Fig. 4c, the car is arranged as a hopper bottom car, the member 19 occupying a position wherein it forms an end wall for the central hopper 13. In this connection it is understood that when thecar is arranged as a hopper bottom car for carrying dumpable material, unless some separating means is provided, the dumpable ma. terial not only occupies the. hopper portions of the car, but also accumulates and occupies the fixed horizontal portion 12 at the ends of the car. The members 19, therefore, when forming hopper end walls, prevent accumulation of dumpable material on the fixed horizontal floor portions 12, thereby obviating the necessity of shoveling dumpable material from the fixed floor portions. .It is well appreciated that certain classes of merchandise cannot be carried to advantage when the car is arranged as a hopper bottom car, there being many advantages in making the car convertible into a flat bottom car in connection with carryin certain lines of merchandise. The movab le members 19 and 20, together with the movable side members 10, make changing the car from a hopper bottom carto a fiat bottom car, and vice versa, a very simple matter.

There may be various modifications of my invention as herein particularly shown and described, and it is my intention to cover all such modifications which do not involve a departure from the spirit and scope of the invention as set forth in the following claims.
